Arguably, our favorite of this year's show, Porsche 918 RSR Hybrid racer debuts. This single-seater combines a 563 hp V8—that spins to over 10,000 rpm—and two electric motors for a total of 767 hp. A flywheel mounted where the passenger normally sits stores braking energy and releases it when the driver pushes the "push to pass" button. This car will be racing. It is as Porsche President called it "A race lab of fuel saving technologies."
